While i really like my rugers i wouldnt personaly get a mini 30 over a sks.
I payed a average of 100 dollars for mine& i use them a bit for plinking^& target shooting.
I think you can still get some of them for about150 dollars or less-
Whats that about 2 or 3 sks,s for the price of one mini ?
Im sure if we still didnt have the billy clitoons ban on chinese firearms& ammo in place& walmart bought sks,s in bulk they could be had for about 75 dollars a piece today for unissured 30.cal semi auto rifles with walmarts buying power.( lotsa luck with that ever happing right?

)
Mine shoot well enough(the one not as well as the other 2).I have never had one break & been using them for 13+ yrs now with many thousands of rounds of ammo thew at least the 2( the nicer looking one im saving from much use)
I have never had a problem with the few30 round mags i have used either with them.
But you can leave them stock& reload there 10 round factory mags real quick with stripper clips with a little practice.
I found out recently(some research on the net)the one i use/shoot the most is really a very early model soviet/chinese- with milled parts etc. Made in 1956-57 & still works great- tho not so pretty- it was 89 dollars before billys ban.
They will work just fine if the shtf to. I got 30.06&270.s etc if the shtf a little further out.
My mate even likes to shoot them some & she dosnt like rifles that have much of a kick to them.
